Hello ALi,
It’s totally possible to install HDP2.3 on a single node, I usually do it on docker centos 6 in order to test new stuff.
I also arrive to manage the migration from HDP 2.2 to HDP 2.3 on a single node and multi node ( Docker) wih Kerberos include.
However, I made a manual upgrade and I didn’t used the Ambari upgrade Maanger.
What kind of problem did you had during this operation?
